Treating desalter water effluent for wash water reuse in a GOSP using a ceramic nanofiltration membrane

摘要

Systems and methods include a Gas and Oil Separation Plant (GOSP)-embedded treatment system for recycling desalter wash water. The system includes: 1) an inlet system providing an inlet stream of desalter water effluent received from at least one desalter of a source; 2) a filtering system in the GOSP including a nanofiltration (NF) membrane configured to filter the desalter water effluent to attain filtered desalter water effluent within a pre-determined wash water threshold for wash water reuse, including: partially desalinating the desalter water effluent to attain a Total Dissolved Solids (TDS) of the desalter water effluent within a pre-determined TDS threshold; and 3) a pump system configured to pump the desalter water effluent through the NF membrane and pump the filtered desalter water effluent to a supply line of the desalter.
